Shawn has serviced our home at least twice. Both times he was very communicative and thorough. I appreciated his friendly nature and willingness to explain everything to me in great detail. It's obvious he is passionate about his job and wants to always do his best for the customer.

I would like to give 5 stars because we are so consistently pleased with Jose's service. He knows our HVAC system very well, and recently installed a smart thermostat quickly and expertly, despite some tricky wiring in our system. While we are very pleased with Jose's work, I must say that the charge for this call, which lasted less than an hour, was ridiculously high, especially considering that we are longtime, faithful customers. Nevertheless, we will stay with Shavitz, because we are so happy with Jose

Shavitz comes through every time! Within 5 minutes Henry S. was able to find what was wrong and discuss potential solutions with me. What I really liked was that he recognized the financial ramifications of each solution and gave me several options to resolve what was wrong. Even better, he explained details about my heating systems that I had never been aware of which will help me in the future!

We had an excellent experience with the technician, Krzysztof, who came to our house to service our new HVAC system. We heard a whistling sound when the furnace went up in temperature. Krzysztof spent considerable time determined to get to the source of the problem--which turned out to be small air pockets in the new humidifier. He then easily corrected the problem. He also went the extra mile to assist us with our new high-tech thermostat, connecting our mobile phone to the thermostat for programming when away from home and taking the time to explain to us how the thermostat worked. Based on our very positive experience, we asked Kryzysztof to be our key contact and technician relating to our maintenance contracts with Shavitz. Krzysztof is a true professional, very knowledgeable and willing to assist in every way.

Krzysztof is simply the best. Always smiling and ever pleasant. He had to tell me my furnace was effectively dead and you could tell it wasn't news he relished giving! And Jennifer in scheduling is delightful. Caring and warm and engaged. Shavitz is the best HVAC company there is!

Cornelius M. serviced our AC today, as part of our annual maintenance contract with Shavitz, who we have happily used for nearly 15 years. He is an outstanding technician, like all of Shavitz's techs. He was thorough, efficient and gave me choices about what additional service and parts we needed, explaining the reasons why. He makes sure that no dirt is dragged into our house and cleans up afterwards. Enjoyed talking to him as well. We appreciate Shavitz and Cornelius and unequivocally recommend them to all our friends in Skokie.

We have used Shavitz for years and they have never failed to provide excellent service. The most recent service visit was on May 9. The technician was Cornelius M. He was courteous, competent, and efficient. At the beginning of the visit, he explained in easy to understand terms what he be doing and at the end, he explained what he had found, i.e. no problems and reviewed his work. He also arranged with the office to make our next appointment. He was outstanding and I would be delighted to have him provide service to us again.

Shavitz was awesome - lousy rainy weather so they kept me informed with regular calls on the appointment status (had to work outside on compressor). Cornelius M., service technician, is a great guy. Did not push equipment, despite my unit being from 1994. Explained everything, was fast, efficient, knowledgeable, and personable. These are people you can trust, and I've had more than few that you can't! If you need something fixed or regular maintenance, my highest recommendation.

New to Skokie, and needed to find a reliable Heating & Cooling Company. Shavitz is just that. From the call to the office, which was helpful, knowledgeable and did everything to get a technician to solve the problem quickly at our home. Our technician Cornelius M. was wonderful. He was professional, nice, patient with all of our questions and most of all so knowledgeable, and an expert in this field. He worked for hours to solve our problem inside and get our heat running, the best he could during this unexpected frigid cold, and will be back to complete the job in early Spring when he can finish out doors so all the necessary work will be complete. We have that date all set already. The price was reasonable for the work done and to be done, and the service plans offered which we did sign up for also reasonable. It will give us a peace of mind to have Shavitz maintaining our future Heating and Cooling needs.
